Please note that the files described below may not include
an annual report for every year that the mine was in operation.
We will endeavor to find the closest annual report to the time period that you request.
This large collection of mining records from the Department of Natural
Resources is organized alphabetically by county and alphabetically by mine name. The
collection is especially useful to those doing corporate research, mine histories,
geological work, and is often referred to when we conduct research for uranium miners who
are trying to document their radon exposure levels.
Mine files consist of two types of reports: "Annual Operator Reports" and "Annual Inspector Information Reports." Information found in these records may include name of mine, kind of operation, mine owner, insurance carrier, mine operator, location of property, production for the year, labor statistics, geological formation, size of deposit/vein, and a description of equipment and structures.
Address all inquiries to the Colorado State Archives. We have search, handling, and copy fees. Please contact us in order to find out the charges for your request.
